To all whom it may concern:

Be it known that 1, Leo R. LEWIS, a citizen z f the United States ofAmerica, and resident of Somerville, in the county of MiddleseX andState of Massachusetts, have invented new and useful Improvements inBinders, of which the following is a specification.

This invention relates to'protective covers or binders for books,particularly for books of the kind which have flexible covers of papersuch as magazines, periodicals, catalogues, samplebooks, pamphlets,briefs, reports, and the like.

b'ects of he invention areto provide a simple, durable, efficient andinexpensive cover for temporary or'permanent use which will givecomplete protection to'the book therein enclosed without renderinginspection or use thereof diflicult and without interfering in any waywith the free action of the leaves. v

The invention comprises a cover, preferably in the form of an integralsheet of a size to enclose the book, astilf, solid filler, and meansattaching the filler to the cover and the book to the filler.. The.cover and filler are preferably separable from each other and from thebook. The thickness of the filler is preferably substantially-that ofthe I book to be covered, and forthe purpose of adapting the cover orbinder to books of different thicknesses the filler is preferablylaminar-and is built up of separate strips of suitable material such aswood or fibre board. The attachmentof the fille'r to the cover is suchas to permit the ready addition or removal of filler strips to make thethickness of the liner conform substantially to the thickness of thebook to be protected, and the connection of the book to the fillerpreferably takes a form which permits the greatest freedomof action ofthe leaves and the book.

For the purpose of illustrating the invention certain embodimentsthereof are shown in the accompanying drawings, in which Fig. 1 is aplan view illustrating the binder in use, a portion of the cover beingbroken away; 7 v

Fig. 2 is a sectional, view on an enlarged scale on the line 2-2 of Fig.1; and,

' Figs. 3, 4: and 5 are partial sectional views similar to Fig. Zshowingmodifications.

As illustrated, the invention compr ses a cover A of tough paperor othersuitable ales; materia ad pted t 99%. the s e '1' Y 7 BINDER,

and back of a book. The cover is preferably I integral and has folds at6 and 7. Within the cover between the folds is a filler B attached tothe cover sheet A in any suitable or desired manner, and attached to thefiller B 18 the magazine or book G which is to be protected. It isdesirable that the thickness of the filler B. be made to conformsubstant ally to the thickness of the book or magazine C, both on thescore of the appearance of the assembled structure and its strength. v

If the book were materially thicker than the filler a strain would bethrown on the back of thebinder especially along the folds 6 and 7 wh chmight result in tearing. If the book were thinner than the filler anunder strain would be thrown on the. connection between the book and thefiller, and the covers A would tend to bend inward and become deformed.Therefore, to make the filler var able in thickness, the filler is madelaminar in form, being built up of juxtaposed strips 6 of suitablematerial such as wood, cardb0ard,fibre board or the like.

The means for attaching filler B to the cover sheet A is such as topermit easy addition orsubtraction of filler strips. Such means maycomprise straps 8 of suitable flexible material such as strong paper orbindersfcloth passing through openings or Slots 9 in the cover sheet ator near the folds 6 and 7 "and extending over the back of the coversheet between said openings, the free ends of the straps extendinginside of the cover sheet and adjacent the top and bottom respectivelyof filler B. These strap ends and the strips 6 of filler B areprovidedwith registering holes, through which pass suitable fastening means,preferably of a removable type such as a flat strip or ribbon offlexible metal 10, the body of which lies along one side of the filler Binside of cover sheet A,and the free ends of which pass through thealigned openings in straps 8 and strips 6 to be there bent'over orclinched as at 11 on the opposite side of the filler. Any desired numberofstraps 8 may be used and more than one ribbon l0 or other fastener ifdesired depending upon the size of the book to be protected. One or bothof the free ends of the straps 8 may be provided with a plurality ofopenings 12 for the fastener, or holes may be punched therein as neededwhen -changing thfithickness of filler B to adapt the binder to books.of different thick mess, .2 Y

The book or magazine C is attached to filler B by one or more hingemembers 13. These hinge members 13 may be formed of any tough flexiblestrip material, preferably cloth and are preferably connected to thefiller B or a portion thereof by a loop. In Figs. 1 and 2 the loop ofthe fabric hinge member 13 extends entirely around the filler B, thethroat of the loop being stitched or otherwise fastened together at 1%adjacent the filler, and the free ends 15 being then nadefast to thebook C. One method of accomplishingthis is to apply a coating ofadhesiveto the free ends 15 and sticking these ends to the outside of the bindersheet 0 of the book near its bound edge as shown in Figs. 2, 3 and 5.Inasmuch as a hinge mem' ber looped entirely about the filler B isadapted to a filler of only one uniform r thickness, a modified form ofattachment of the hinge strip is disclosed in Fig; 3 wherein the hingestrip 18 is looped around one of the filler strips 6, preferably themiddle strip as shown. This permits filler strips Z) to be added to ortaken from the filler B without change in the attaching means for thebook.

It is sometimes possible to secure afirmer anchorage or attachment ofthe book to the tiller B by having the free ends of the hinge member 13-or 13 pass through the back of the book or magazine to the interiorbetween two signatures, as shown at 15 (Fig. 5), said ends being guinmedon the outer sides and attached inside the book by moistening them. Orthese attaching ends might extend through a slot in the back of asignature instead of between signatures, especially in the ease of athin book. A further advantage of such inside attachment is that thereis no interference with the later permanent binding of the book.

The invention is also applicable to the ring type of temporary binder.Such adaptation of theinventi'on is disclosed in Fig. 5 wherein thestrips 6" forming the laminar filler B are wedge shaped in crosssection, or sectors of a circle Whose center corresponds, approximatelyto the center of the separable ring 17 which extends through openings 18and 19 in strips 6 and cover A respectively, thus uniting the filler andthe cover. The strips Z) are all identical and may be added or removedas before, according to the thickness of the book. A flexible hingemember 20 similar to that disclosed in the 'othermod'ifications employedfor attaching the magazine C to the filler B. The loop of hinge member20' may pass around all or any number of the strips '6, and theattaching ends may extend between signatures as shown at 15, or befastened to the outside of the book as Fig.

From the foregoing it will be seen that the binder may be quickly andeasily applied to magazines and other books of widely varyingthicknesses, and as easily re moved' by taking out the fastener 10, or1:7) whereupon the parts may be readily disassembled and all, savepossibly the hinge 7 member 13 which is stuck to the book, may be usedagain. The binder is light, compact and cheap. It adds little to thebulk of the book and does not interfere in the slightest degree with thefull and free epen ing of the book and manipulation of the leaves, whileat the same time affording a firm and solid support for the bound edgeof the book and the back of the binder. The binder may be reversedinside out, or turned top for bottom or back for front. And the enclosedbook or pamphlet may afterward be permanently bound or become part of aseries in permanent bindin In the forms shown in Figs. 1 to 4 no metalor rigid partof any kind is exposed on the exterior of the binder; hencethere can be no inarring of tables or racks, nor any denting, nicking,scratching'or tearing of books, magazines or papers which come incontact with the binder.
